Important Note
Some vehicles with IMMO or PATS may require key programming after installation. This is normal.
For a 100% plug-and-play solution with no relearns, your original ECU must be sent in for cloning. We transfer all security data to the replacement unit.
👉Add the cloning service as a bundle at checkout — $200 CAD / $140 USD
A prepaid shipping label will be emailed to you.
If cloning is not selected, the ECU will be VIN programmed, and a key relearn will be required after installation.

The ECM arrived quickly and was exactly as described for my 2011 Buick LaCrosse. Installation was straightforward, and it fit perfectly without any additional programming on my end. The engine runs smoothly now, and I’m really impressed with how seamless the whole process was. Customer support was also responsive when I had a couple of questions, which made things easier.

I was a bit nervous ordering an ECM online, but this 2011 Buick LaCrosse ECU exceeded my expectations. It arrived much faster than I anticipated, carefully packaged, and ready to go right out of the box. Installing it was surprisingly straightforward—I didn’t have to fiddle with any complicated programming since it came VIN programmed. Once installed, my car fired up immediately and has been running smoothly ever since. It’s such a relief to have my LaCrosse back on the road without any engine hiccups. Definitely a solid buy for anyone needing a hassle-free replacement.
